The third level centers around controlling blood pressure and proteinuria as a means of preventing or delaying the progression of CKD.[8] The available treatments for CKD are currently quite limited, primarily focusing on strategies such as controlling protein intake, reducing blood sugar and blood lipids, inhibiting the renin-angiotensin-aldosterone system, and addressing poor lifestyle habits to slow the progression of the disease. The gene discussed is REN; the disease is chronic kidney disease.
